Microwave-assisted methanolysis was performed to fractionate a mixture of fatty acid methyl-esters from the cuticles of various wild plants and agricultural wastes. A combination of hydrothermal pretreatment and enzymatic hydrolysis effectively removed hemicellulose and cellulose to afford plant cuticles concentrated in residual materials. The subsequent methanolysis treatment afforded bio-oil from plant cuticles in ∼10% yield with a maximum higher heating value (HHV) of 32 MJ kg from bagasse. The proposed cascading treatments allow the total use of herbaceous soft biomass by utilizing hemicellulose and cellulose fractions as well as plant cuticles to produce bio-oils with high HHVs.
采用微波辅助甲醇ysis法对来自各种野生植物和农业废弃物表皮的脂肪酸甲酯混合物进行分馏。水热预处理和酶水解相结合有效地去除了半纤维素和纤维素，从而得到富含残余物的植物表皮。随后的甲醇ysis处理从植物表皮中获得了生物油，产率约为10%，甘蔗渣的最高高热值（HHV）为32 MJ/kg。所提出的级联处理方法通过利用半纤维素和纤维素部分以及植物表皮来生产具有高HHV的生物油，从而实现了草本软生物质的全部利用。
